7.3 Impressionism & Post-Impressionism

Impressionism (c. 1870–1890)

In April 1874, a group of radical Parisian artists—calling themselves the Société Anonyme des Artistes Peintres, Sculpteurs, Graveurs—mounted an independent exhibition in the studio of photographer Nadar, bypassing the official state-sponsored Salon. The movement earned its name when art critic Louis Leroy derisively seized upon Claude Monet's painting, Impression, Sunrise (1872), writing that wallpaper in its embryonic state was more finished than Monet's seascape. The artists embraced the label, launching Impressionism as one of the most transformative movements in modern art history.

Impressionism rejected academic painting's reliance on historical themes, meticulous blending, and studio-bound lighting. Instead, Impressionists turned their attention to modern urban life, Parisian leisure, and the optical study of light, climate, and color as perceived in fleeting moments (instantanéité).

Technological and Scientific Catalysts

Several 19th-century technological and scientific developments directly catalyzed the Impressionist revolution:

• Portable Collapsible Metal Paint Tubes: Invented by American portrait painter John Rand in 1841, pre-mixed oil paints in tin tubes freed artists from grinding pigments in the studio. Artists could now carry their materials directly into nature to paint en plein air (outdoors).
• Synthetic Industrial Pigments: Advances in chemistry introduced vibrant new synthetic colors, such as cobalt blue, cerulean, emerald green, and chrome yellow, expanding the artist's palette far beyond traditional earth tones.
• Optical Color Theory: Scientists like Michel Eugène Chevreul published influential treatises on the law of simultaneous contrast of colors, demonstrating that complementary colors placed side by side intensify each other's visual brilliance.

Technical and Compositional Characteristics

Stylistically, Impressionist paintings exhibit distinct physical traits:

• Optical Color Mixing: Instead of physically blending paints on a palette, artists applied short, dabbed strokes of pure, unmixed color directly onto the canvas. From a distance, the viewer's eye visually blends these adjacent colors, producing an optical vibration far more luminous than flat mixed color.
• Colored Shadows: Rejecting academic black or dark brown shadows, Impressionists observed that shadows contain complementary colors reflecting ambient light (e.g., blue or violet shadows on sunlit snow).
• Asymmetrical Cropping & Flattened Space: Influenced by high-speed photography and imported Japanese woodblock prints (ukiyo-e by artists like Hokusai and Hiroshige), Impressionists utilized steep diagonals, off-center focal points, and abrupt spatial cropping.

Key Impressionist Figures

• Édouard Manet: The intellectual bridge between Realism and Impressionism. Manet scandalized the 1863 Salon des Refusés with Le Déjeuner sur l'herbe (Luncheon on the Grass) and Olympia, featuring unidealized contemporary women gazing directly at the viewer, painted with flattened tonal planes and bold outlines that emphasized canvas flatly.
• Claude Monet: The quintessential Impressionist. Monet painted extensive series of the same subject—Haystacks, Rouen Cathedral, and his water garden at Giverny (Water Lilies)—at different times of day and across seasons to document how light systematically transforms color.
• Pierre-Auguste Renoir: Captured dappled sunlight, warmth, and buoyant middle-class leisure in outdoor Parisian social venues, most famously in Bal du moulin de la Galette (1876).
• Edgar Degas: Focused on indoor artificial lighting, movement, and psychological tension. A master draughtsman, Degas depicted ballet dancers, bathers, and racehorses from unexpected overhead angles, heavily influenced by ukiyo-e spatial design.
• Mary Cassatt: An American artist who joined Degas's circle in Paris. Cassatt brought technical mastery of pastel and printmaking to intimate, dignified scenes of mothers and children (The Child's Bath), documenting female domestic agency without sentimental cliché.

Post-Impressionism (c. 1886–1905)

Coined by British art critic Roger Fry for a 1910 exhibition, Post-Impressionism describes a diverse group of artists who built upon Impressionism's vivid palette and rejection of academic illusionism, but rejected its fleeting, formless quality. Post-Impressionists felt Impressionism sacrificed structural permanence and emotional weight for momentary light effects. Post-Impressionism split into two primary stylistic directions:

The Structural and Analytical Branch

• Georges Seurat: Developed Pointillism (or Divisionism), a methodical technique of applying tiny, meticulous dots of pure color grounded in scientific optics. In A Sunday on La Grande Jatte (1884–1886), Seurat froze Parisian figures into a statuesque, timeless geometric order, turning Impressionist leisure into monumental classical structure.
• Paul Cézanne: Sought to "make of Impressionism something solid and durable, like the art of the museums." Working in Aix-en-Provence, Cézanne analyzed nature by reducing landscape and still-life forms to fundamental geometric volumes (the cylinder, sphere, and cone). Cézanne abandoned traditional single-point linear perspective, employing multiple viewpoints simultaneously and applying color in flat, constructive brushstrokes (patches). In Mont Sainte-Victoire and his still lifes, Cézanne flattened spatial depth, providing the structural foundation for 20th-century Cubism.

The Expressive and Symbolic Branch

• Vincent van Gogh: Transformed color and brushwork into direct conduits for intense psychological and spiritual emotion. In The Starry Night (1889) and Sunflowers, Van Gogh applied thick, swirling impasto with rhythmic energy, using expressive, non-naturalistic color to convey existential angst and cosmic ecstasy.
• Paul Gauguin: Rejected Western industrialism, relocating to Brittany and later Tahiti. Gauguin developed Synthetism (or Cloisonnism), characterized by flat areas of bold, unmodulated color enclosed by dark outlines. In Where Do We Come From? What Are We? Where Are We Going? (1897), Gauguin combined Polynesian myth, Christian allegory, and expressive color into a grand philosophical statement.
